Now that we are on the MSD (and if you don't want to be stuck on the side of the road with burned out points (and Corvette guys laughing at you), you SHOULD have an MSD), we should take a few moments to show you how to hook it up so you don't turn the key and wonder why your motor isn't running (or why your tach isn't working) while your friends start laughing at you.
Now for the question that has been asked us at least a million times. How do I hook up my MSD box?
To begin with, you will need to cut the blue and pink wires that come out of the box by the distributor lead. The distributor lead has the plastic fitting on the end (you can see it in the picture). You will also need to snip the green wire in half. (It comes as a loop from MSD). We heat shrink all those wires together to the distributor lead so they can't short out on something.
Coil wire hook up on MSD is as follows. This works if you are using a MSD distributor.
Find the pink and white wires that come out of the middle of the MSD box--they are covered in a plastic sheath. Cut them off to about 6 inches long and remove the plastic sheathing so you can see the wires and work with them. Cut the white wire off to about 3 inches long. Put a male 1/4 spade connector on the end of the pink wire (which is hopefully still 6 inches long). Make sure you heat shrink the junction between the spade and the wire to give it strength so it will not fatigue out over time.
Take the pink wire labeled "Coil" from the wiring harness and...
Then, connect it to the pink wire from the MSD box you just put the 1/4 male spade on (complete with the recommended heat shrink on the wire to connector joint). Notice how we put an additional heat shrink over the entire joint to make sure it can't come apart or short out somewhere. (We have not yet "shrunk" the heat shrink tubing in the bottom picture.) Almost ALL electrical failures are failures of connections--not failures of the part that is "not working."
